We declare no confl ict of interest. ABSTRACT We evaluated the DMFT (decayed, missing and fi lled teeth) index and the prevalence of candidia-sis, linear gingival erythema, oral hairy leukoplakia, herpes simplex, aphthous ulcers, Kaposi's sar-coma and lymphoma, as well as the association with TCD4 count, viral load (VL) and antiretroviral therapy (ART) in 140 HIV-infected adult individuals. A standardized examination to determine the DMFT index and the presence of oral lesions was conducted. Demographic data, TCD4 count and use of ART were obtained from medical records. A high number of decayed teeth detected among patients undergoing ART resulted in a mean DMFT of 16.9 teeth. It was observed that 24.2% of the individuals had at least one oral lesion. Candidiasis was the most frequent lesion and was associated with the TCD4 count. Oral hairy leukoplakia was associated with an increased VL. Regular use of ART was inversely associated with the occurrence of lesions. Overall, the studied population showed low prevalence of oral lesions and high DMFT index. The use of ART seems to reduce the occurrence of these lesions. Higher TCD4 count and a lower VL were associated with an improved oral health status in HIV+ individuals.

Non-Hodgkin lymphoma is the second most common neoplasm of the head and neck after squamous cell carcinoma. However, it accounts for only 3.5% of all malignancies of the oral cavity. Oral lesions are often a component of disseminated disease process that may involve regional lymph nodes or may at times represent the primary extra nodal form of the disease. Although, isolated oral lymphoma in adults is extremely rare, this paper presents a patient with Burkitt lymphoma in an adult male with atypical clinical presentation primarily involving the oral soft tissue. It is believed that the prognosis of Burkitt lymphoma depends on the extent of the disease, the patient's age, and the timing of diagnosis. Therefore, the role of the dentist in the early diagnosis and prompt referral of patients with Burkitt lymphoma cannot be overemphasized.

pubescens St. Hil.-Sapindaceae em função da temperatura Seedling emergence of Magonia pubescens St. Hil.-Sapindaceae a function of temperature RESUMO: O timbó (Magonia pubescens St. Hil.-Sapindaceae) é uma das espécies medicinais nativas, com sementes ricas em saponina, usadas para a limpeza de úlceras, enquanto o chá da casca é usado para tratar feridas e o das raízes como calmante. O objetivo foi verificar a influência da temperatura na emergência de plântulas. Foi utilizado o delineamento experimental de blocos casualizados com cinco repetições de 50 sementes, e os seguintes tratamentos: a) 5 °C, b) 10 °C, c) 15 ºC, d) 20 ºC, e) 25 ºC, f) 30 ºC, g) 35 ºC, h) 40 °C e i) 45 °C. Nas temperaturas de 25 e 30 °C, a porcentagem de emergência foi de 94 e 88%, respectivamente, enquanto nas temperaturas de 5, 10, 15, 40 e 45 °C não houve germinação. O índice de velocidade de emergência foi maior na temperatura de 30 °C (0,72). As temperaturas de 5, 10, 15, 40 e 45 °C são prejudiciais para a germinação de sementes de timbó. Sendo a temperatura de 30 ºC a mais indicada para a germinação e emergência de plântulas de M. pubescens.
